The motion based clock face has horrible lag. You can set always-on for the clock but it will use a different clock face than the one you selected. If you select analog it uses a decent clock face, good enough that I would want it as my actual clock face but apparently fit bit does not allow that.
So I am stuck with two analog clock faces: one that is "always-on" which changes into a different one when I move my wrist.
The least bad solution I found is this:
set the "Always On Display" to "On" and the "Screen Wake" to "Manual(Button)"
in the options you get when you click the button and swipe down (third icon on top).
That will keep the default analog clock face always on without the annoying lag, just like a real watch,
and it will not replace it by some other clock face in mid motion, but you do have to click the button to activate the screen for other things, which is fine by me.
